and my dog was sniffing like that yesterday as well while out in the woods, probably bear.

With her sniffing the branches up high and not being terribly excited, I would say, without doubt, that it was bear. Totally different body language from predator to prey tracks.

Thanks everyone. : )

Now that I have thought about it more, I take the "...without doubt..." part back. Her hackles weren't up, which they usually are with fresh predator tracks. Probably bear though, as she was a bit skittish in the video.
Fresh rabbit, raccoon and deer tracks get her whimpering and whining in excitement. With coyote, big cat and bear tracks just getting a lot of nose action and hackles.

Thanks Bob, it was a good hike. Katie was a threat to her leader's lunch...Sierra probably has nightmares over Katie. ; )

NQ, it's about time you responded to a Katie hike. Not a lot of 'dog people' on this site, so you are our 'bread and butter'. I always consider 75% of the hits our TR's get are probably from you. : )
Katie is sucking up big time in that last photo. : )
